    2 The first task in building an Ecopath model is to define the model’s functional groups (called Groups or Boxes). Groups are species or collections of species that share similar population dynamics and ecological function. See [[Defining the system.htm|Defining the system]] for more on how to define groups.

    4 To add and edit functional groups to an Ecopath model, choose the ''Edit groups...'' option on the [[Ecopath menu.htm|Ecopath menu]] on the ''Menu bar''. This will open a form where you can add, delete, name and sort the functional groups in your model.

    8 After adding model groups on the ''Edit groups'' form, you can proceed to the ''Input data'' forms to enter parameters for your groups (i.e., [[Basic input.htm|Basic input]], [[Diet composition.htm|Diet composition]], [[Detritus fate.htm|Detritus fate]] and [[Other production.htm|Other production]] forms, accessible in the ''Navigator window'' under the ''Input data'' node).

    2222You must define whether a functional group is a primary producer, consumer or detritus by checking the appropriate box.

    24  * Primary producers (producers) obtain all of their energy from photosynthesis. By definition, their [[Trophic level decomposition.htm|trophic level]] is 1.

    2525 
    2626 
    2727 * Consumers obtain their energy by consuming other organisms. They have trophic level > 1. 
    28  * Detritus groups are dead. Note that you must enter at least one detritus group and you can have as many detritus groups as you like. Note also that detritus groups must be placed after all living groups (i.e., they must have a higher group number than the last living group). You must also specify where the surplus detritus (left over after feeding by detritivores) will go using the [[Detritus fate.htm|Detritus fate]] form.

    44 The ''Edit groups'' form allows you to create groups representing life history stages or stanzas for species that have complex trophic ontogeny (see introductory material on [[Representation of multi stanza.htm|multi-stanza groups]] (Chapter 2 of the EwE6 User Guide) for more information on how these groups are modelled in Ecopath, Ecosim and Ecospace).
